Description The Pentium II 400 MHz Xeon 32-bit processor is the true successor to the Pentium Pro, which was Intel's first product designed specifically for server and workstation systems. Like the Pentium Pro, the Xeon processor supports SMP (symmetric multi-processing), up to eight CPUs in a single system. The Xeon incorporates Intel's advanced 'Deschutes' .25 micron core together with high-speed cache memory into a processor that is blindingly fast and very efficient in its data handling. The Xeon's other distinguishing attribute is its L2 cache memory which is incorporated into the processor cartridge. This cache memory runs at full processor clock speed, which means that the processor has to waste very few clock cycles idle, waiting for the memory to 'catch up' and feed it more data. The L2 cache also supports ECC (Error Correction Code), which allows the memory to detect and correct single-bit data errors on the fly, protecting the integrity of your important data so that it does not become corrupted during normal use. The Xeon can also support large amounts of L2 cache memory; This version supports 1 MB cache. The Xeon has inherited MMX technology multimedia enhancements from the Pentium II, and like the faster Pentium II's, the Xeon runs on a 100 MHz system bus, allowing it faster access to main system memory. Also like the Pentium II, Xeon processors require a special retention mechanism to secure them to the motherboard, preventing shock or vibration damage. IBM backs this product with a three-year customer carry-in exchange warranty.
